domain of f(x)=-4sqrt(x-4)

domain

f (x) = - 4 x - 4

x \geq 4

Interval Notation

[4, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 4

The function domain

x \geq 4

(- 2, 4), (3, - 3)

2 x - 5 y = 15, (\frac{1}{2}, - \frac{3}{4})

\frac{- 7 ( 4 + x )}{( 2 ^{x} - 8 ) ( - 1 - 3 x ) ^{2}}

y = 20 - 3 x

ln (7 - 6 x^{2})

What is the domain of f(x)=-4sqrt(x-4) ?
The domain of f(x)=-4sqrt(x-4) is x>= 4
